+# Chokidar [![Weekly downloads](https://img.shields.io/npm/dw/chokidar.svg)](https://github.com/paulmillr/chokidar)
+
+> Minimal and efficient cross-platform file watching library
+
+## Why?
+
+There are many reasons to prefer Chokidar to raw fs.watch / fs.watchFile in 2024:
+
+- Events are properly reported
+    - macOS events report filenames
+    - events are not reported twice
+    - changes are reported as add / change / unlink instead of useless `rename`
+- Atomic writes are supported, using `atomic` option
+    - Some file editors use them
+- Chunked writes are supported, using `awaitWriteFinish` option
+    - Large files are commonly written in chunks
+- File / dir filtering is supported
+- Symbolic links are supported
+- Recursive watching is always supported, instead of partial when using raw events
+    - Includes a way to limit recursion depth
+
+Chokidar relies on the Node.js core `fs` module, but when using
+`fs.watch` and `fs.watchFile` for watching, it normalizes the events it
+receives, often checking for truth by getting file stats and/or dir contents.
+The `fs.watch`-based implementation is the default, which
+avoids polling and keeps CPU usage down. Be advised that chokidar will initiate
+watchers recursively for everything within scope of the paths that have been
+specified, so be judicious about not wasting system resources by watching much
+more than needed. For some cases, `fs.watchFile`, which utilizes polling and uses more resources, is used.
+
+Made for [Brunch](https://brunch.io/) in 2012,
+it is now used in [~30 million repositories](https://www.npmjs.com/browse/depended/chokidar) and
+has proven itself in production environments.
+
+**Sep 2024 update:** v4 is out! It decreases dependency count from 13 to 1, removes
+support for globs, adds support for ESM / Common.js modules, and bumps minimum node.js version from v8 to v14.
+Check out [upgrading](#upgrading).
+
+## Getting started
+
+Install with npm:
+
+```sh
+npm install chokidar
+```
+
+Use it in your code:
+
+```javascript
+import chokidar from 'chokidar';
+
+// One-liner for current directory
+chokidar.watch('.').on('all', (event, path) => {
+  console.log(event, path);
+});
+
+
+// Extended options
+// ----------------
+
+// Initialize watcher.
+const watcher = chokidar.watch('file, dir, or array', {
+  ignored: (path, stats) => stats?.isFile() && !path.endsWith('.js'), // only watch js files
+  persistent: true
+});
+
+// Something to use when events are received.
+const log = console.log.bind(console);
+// Add event listeners.
+watcher
+  .on('add', path => log(`File ${path} has been added`))
+  .on('change', path => log(`File ${path} has been changed`))
+  .on('unlink', path => log(`File ${path} has been removed`));
+
+// More possible events.
+watcher
+  .on('addDir', path => log(`Directory ${path} has been added`))
+  .on('unlinkDir', path => log(`Directory ${path} has been removed`))
+  .on('error', error => log(`Watcher error: ${error}`))
+  .on('ready', () => log('Initial scan complete. Ready for changes'))
+  .on('raw', (event, path, details) => { // internal
+    log('Raw event info:', event, path, details);
+  });
+
+// 'add', 'addDir' and 'change' events also receive stat() results as second
+// argument when available: https://nodejs.org/api/fs.html#fs_class_fs_stats
+watcher.on('change', (path, stats) => {
+  if (stats) console.log(`File ${path} changed size to ${stats.size}`);
+});
+
+// Watch new files.
+watcher.add('new-file');
+watcher.add(['new-file-2', 'new-file-3']);
+
+// Get list of actual paths being watched on the filesystem
+let watchedPaths = watcher.getWatched();
+
+// Un-watch some files.
+await watcher.unwatch('new-file');
+
+// Stop watching. The method is async!
+await watcher.close().then(() => console.log('closed'));
+
+// Full list of options. See below for descriptions.
+// Do not use this example!
+chokidar.watch('file', {
+  persistent: true,
+
+  // ignore .txt files
+  ignored: (file) => file.endsWith('.txt'),
+  // watch only .txt files
+  // ignored: (file, _stats) => _stats?.isFile() && !file.endsWith('.txt'),
+
+  awaitWriteFinish: true, // emit single event when chunked writes are completed
+  atomic: true, // emit proper events when "atomic writes" (mv _tmp file) are used
+
+  // The options also allow specifying custom intervals in ms
+  // awaitWriteFinish: {
+  //   stabilityThreshold: 2000,
+  //   pollInterval: 100
+  // },
+  // atomic: 100,
+
+  interval: 100,
+  binaryInterval: 300,
+
+  cwd: '.',
+  depth: 99,
+
+  followSymlinks: true,
+  ignoreInitial: false,
+  ignorePermissionErrors: false,
+  usePolling: false,
+  alwaysStat: false,
+});
+
+```
+
+`chokidar.watch(paths, [options])`
+
+* `paths` (string or array of strings). Paths to files, dirs to be watched
+recursively.
+* `options` (object) Options object as defined below:
+
+#### Persistence
+
+* `persistent` (default: `true`). Indicates whether the process
+should continue to run as long as files are being watched.
+
+#### Path filtering
+
+* `ignored` function, regex, or path. Defines files/paths to be ignored.
+The whole relative or absolute path is tested, not just filename. If a function with two arguments
+is provided, it gets called twice per path - once with a single argument (the path), second
+time with two arguments (the path and the
+[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
+object of that path).
+* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while
+instantiating the watching as chokidar discovers these file paths (before the `ready` event).
+* `followSymlinks` (default: `true`). When `false`, only the
+symlinks themselves will be watched for changes instead of following
+the link references and bubbling events through the link's path.
+* `cwd` (no default). The base directory from which watch `paths` are to be
+derived. Paths emitted with events will be relative to this.
+
+#### Performance
+
+* `usePolling` (default: `false`).
+Whether to use fs.watchFile (backed by polling), or fs.watch. If polling
+leads to high CPU utilization, consider setting this to `false`. It is
+typically necessary to **set this to `true` to successfully watch files over
+a network**, and it may be necessary to successfully watch files in other
+non-standard situations. Setting to `true` explicitly on MacOS overrides the
+`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable
+to true (1) or false (0) in order to override this option.
+* _Polling-specific settings_ (effective when `usePolling: true`)
+  * `interval` (default: `100`). Interval of file system polling, in milliseconds. You may also
+    set the CHOKIDAR_INTERVAL env variable to override this option.
+  * `binaryInterval` (default: `300`). Interval of file system
+  polling for binary files.
+  ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json))
+* `alwaysStat` (default: `false`). If relying upon the
+[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
+object that may get passed with `add`, `addDir`, and `change` events, set
+this to `true` to ensure it is provided even in cases where it wasn't
+already available from the underlying watch events.
+* `depth` (default: `undefined`). If set, limits how many levels of
+subdirectories will be traversed.
+* `awaitWriteFinish` (default: `false`).
+By default, the `add` event will fire when a file first appears on disk, before
+the entire file has been written. Furthermore, in some cases some `change`
+events will be emitted while the file is being written. In some cases,
+especially when watching for large files there will be a need to wait for the
+write operation to finish before responding to a file creation or modification.
+Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size,
+holding its `add` and `change` events until the size does not change for a
+configurable amount of time. The appropriate duration setting is heavily
+dependent on the OS and hardware. For accurate detection this parameter should
+be relatively high, making file watching much less responsive.
+Use with caution.
+  * *`options.awaitWriteFinish` can be set to an object in order to adjust
+  timing params:*
+  * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in
+  milliseconds for a file size to remain constant before emitting its event.
+  * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval, in milliseconds.
+
+#### Errors
+
+* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files
+that don't have read permissions if possible. If watching fails due to `EPERM`
+or `EACCES` with this set to `true`, the errors will be suppressed silently.
+* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`).
+Automatically filters out artifacts that occur when using editors that use
+"atomic writes" instead of writing directly to the source file. If a file is
+re-added within 100 ms of being deleted, Chokidar emits a `change` event
+rather than `unlink` then `add`. If the default of 100 ms does not work well
+for you, you can override it by setting `atomic` to a custom value, in
+milliseconds.
+
+### Methods & Events
+
+`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`:
+
+* `.add(path / paths)`: Add files, directories for tracking.
+Takes an array of strings or just one string.
+* `.on(event, callback)`: Listen for an FS event.
+Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`,
+`raw`, `error`.
+Additionally `all` is available which gets emitted with the underlying event
+name and path for every event other than `ready`, `raw`, and `error`.  `raw` is internal, use it carefully.
+* `.unwatch(path / paths)`: Stop watching files or directories.
+Takes an array of strings or just one string.
+* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen.
+* `.getWatched()`: Returns an object representing all the paths on the file
+system being watched by this `FSWatcher` instance. The object's keys are all the
+directories (using absolute paths unless the `cwd` option was used), and the
+values are arrays of the names of the items contained in each directory.
+
+### CLI
+
+Check out third party [chokidar-cli](https://github.com/open-cli-tools/chokidar-cli),
+which allows to execute a command on each change, or get a stdio stream of change events.
+
+## Troubleshooting
+
+Sometimes, Chokidar runs out of file handles, causing `EMFILE` and `ENOSP` errors:
+
+* `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell`
+* `Error: watch /home/ ENOSPC`
+
+There are two things that can cause it.
+
+1. Exhausted file handles for generic fs operations
+    - Can be solved by using [graceful-fs](https://www.npmjs.com/package/graceful-fs),
+      which can monkey-patch native `fs` module used by chokidar: `let fs = require('fs'); let grfs = require('graceful-fs'); grfs.gracefulify(fs);`
+    - Can also be solved by tuning OS: `echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p`.
+2. Exhausted file handles for `fs.watch`
+    - Can't seem to be solved by graceful-fs or OS tuning
+    - It's possible to start using `usePolling: true`, which will switch backend to resource-intensive `fs.watchFile`
+
+All fsevents-related issues (`WARN optional dep failed`, `fsevents is not a constructor`) are solved by upgrading to v4+.
+
+## Changelog
+
+- **v4 (Sep 2024):** remove glob support and bundled fsevents. Decrease dependency count from 13 to 1. Rewrite in typescript. Bumps minimum node.js requirement to v14+
+- **v3 (Apr 2019):** massive CPU & RAM consumption improvements; reduces deps / package size by a factor of 17x and bumps Node.js requirement to v8.16+.
+- **v2 (Dec 2017):** globs are now posix-style-only. Tons of bugfixes.
+- **v1 (Apr 2015):** glob support, symlink support, tons of bugfixes. Node 0.8+ is supported
+- **v0.1 (Apr 2012):** Initial release, extracted from [Brunch](https://github.com/brunch/brunch/blob/9847a065aea300da99bd0753f90354cde9de1261/src/helpers.coffee#L66)
+
+### Upgrading
+
+If you've used globs before and want do replicate the functionality with v4:
+
+```js
+// v3
+chok.watch('**/*.js');
+chok.watch("./directory/**/*");
+
+// v4
+chok.watch('.', {
+  ignored: (path, stats) => stats?.isFile() && !path.endsWith('.js'), // only watch js files
+});
+chok.watch('./directory');
+
+// other way
+import { glob } from 'node:fs/promises';
+const watcher = watch(await Array.fromAsync(glob('**/*.js')));
+
+// unwatching
+// v3
+chok.unwatch('**/*.js');
+// v4
+chok.unwatch(await glob('**/*.js'));
+```
+
+## Also
+
+Why was chokidar named this way? What's the meaning behind it?
+
+>Chowkidar is a transliteration of a Hindi word meaning 'watchman, gatekeeper', चौकीदार. This ultimately comes from Sanskrit _ चतुष्क_ (crossway, quadrangle, consisting-of-four). This word is also used in other languages like Urdu as (چوکیدار) which is widely used in Pakistan and India.

+## API
+
+`const stream = readdirp(root[, options])` — **Stream API**
+
+- Reads given root recursively and returns a `stream` of [entry infos](#entryinfo)
+- Optionally can be used like `for await (const entry of stream)` with node.js 10+ (`asyncIterator`).
+- `on('data', (entry) => {})` [entry info](#entryinfo) for every file / dir.
+- `on('warn', (error) => {})` non-fatal `Error` that prevents a file / dir from being processed. Example: inaccessible to the user.
+- `on('error', (error) => {})` fatal `Error` which also ends the stream. Example: illegal options where passed.
+- `on('end')` — we are done. Called when all entries were found and no more will be emitted.
+- `on('close')` — stream is destroyed via `stream.destroy()`.
+  Could be useful if you want to manually abort even on a non fatal error.
+  At that point the stream is no longer `readable` and no more entries, warning or errors are emitted
+- To learn more about streams, consult the very detailed [nodejs streams documentation](https://nodejs.org/api/stream.html)
+  or the [stream-handbook](https://github.com/substack/stream-handbook)
+
+`const entries = await readdirp.promise(root[, options])` — **Promise API**. Returns a list of [entry infos](#entryinfo).
+
+First argument is awalys `root`, path in which to start reading and recursing into subdirectories.
+
+### options
+
+- `fileFilter`: filter to include or exclude files
+    - **Function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry
+- `directoryFilter`: filter to include/exclude directories found and to recurse into. Directories that do not pass a filter will not be recursed into.
+- `depth: 5`: depth at which to stop recursing even if more subdirectories are found
+- `type: 'files'`: determines if data events on the stream should be emitted for `'files'` (default), `'directories'`, `'files_directories'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes.
+- `alwaysStat: false`: always return `stats` property for every file. Default is `false`, readdirp will return `Dirent` entries. Setting it to `true` can double readdir execution time - use it only when you need file `size`, `mtime` etc. Cannot be enabled on node <10.10.0.
+- `lstat: false`: include symlink entries in the stream along with files. When `true`, `fs.lstat` would be used instead of `fs.stat`
+
+### `EntryInfo`
+
+Has the following properties:
+
+- `path: 'assets/javascripts/react.js'`: path to the file/directory (relative to given root)
+- `fullPath: '/Users/dev/projects/app/assets/javascripts/react.js'`: full path to the file/directory found
+- `basename: 'react.js'`: name of the file/directory
+- `dirent: fs.Dirent`: built-in [dir entry object](https://nodejs.org/api/fs.html#fs_class_fs_dirent) - only with `alwaysStat: false`
+- `stats: fs.Stats`: built in [stat object](https://nodejs.org/api/fs.html#fs_class_fs_stats) - only with `alwaysStat: true`
+
+## Changelog
+
+- 4.0 (Aug 25, 2024) rewritten in typescript, producing hybrid common.js / esm module.
+    - Remove glob support and all dependencies
+    - Make sure you're using `let {readdirp} = require('readdirp')` in common.js
+- 3.5 (Oct 13, 2020) disallows recursive directory-based symlinks.
+  Before, it could have entered infinite loop.
+- 3.4 (Mar 19, 2020) adds support for directory-based symlinks.
+- 3.3 (Dec 6, 2019) stabilizes RAM consumption and enables perf management with `highWaterMark` option. Fixes race conditions related to `for-await` looping.
+- 3.2 (Oct 14, 2019) improves performance by 250% and makes streams implementation more idiomatic.
+- 3.1 (Jul 7, 2019) brings `bigint` support to `stat` output on Windows. This is backwards-incompatible for some cases. Be careful. It you use it incorrectly, you'll see "TypeError: Cannot mix BigInt and other types, use explicit conversions".
+- 3.0 brings huge performance improvements and stream backpressure support.
+- Upgrading 2.x to 3.x:
+    - Signature changed from `readdirp(options)` to `readdirp(root, options)`
+    - Replaced callback API with promise API.
+    - Renamed `entryType` option to `type`
+    - Renamed `entryType: 'both'` to `'files_directories'`
+    - `EntryInfo`
+        - Renamed `stat` to `stats`
+            - Emitted only when `alwaysStat: true`
+            - `dirent` is emitted instead of `stats` by default with `alwaysStat: false`
+        - Renamed `name` to `basename`
+        - Removed `parentDir` and `fullParentDir` properties
+- Supported node.js versions:
+    - 4.x: node 14+
+    - 3.x: node 8+
+    - 2.x: node 0.6+
